Application filed August 4,

To all whom it my concern: Be it known that I, IVILLIAM A. PRINGLE',

Niagara Falls, in the county of Niagara and State of New York, have invented certain new andnseful Improvements in Delivery thefollowing is a full, clear, and'exact dein the art towhich it appertains to make and usefthe same, a This invention relates to printing mechaof this character adapted for delivering sheets cut from one or more traveling webs upon which printing has been effected.

One of the objects of the invention is to above character such that the severed portions of the web are delivered in amore efficient manner from the cutting mechanism than it has been possibleto performsuch-operation in delivery mechanism as hitherto constructed.

Another object thereof is to provide mechanism wherein the severed sheets will not interfere with one another when theyiare be conveniently piled one upon the other in superimposed relation.

Other objectswill be in part obvious and in part pointed out hereinafter.

The invention accordinglyconsists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the appli-' cation of which will be indicated in the fol-.

In the accompanying drawings wherein is bodiments 'of my invention, Figure 1 is a view in side elevation thereof. Fig. 2 is a top'plan view. Fig. 3 isa view in plan upon an enlargedscale showing the corrugated feed rolls for feeding the severed sheets. Fig. 4 is a vertical sectional viaw..; taken longitudinally of the mechanism.

Fig; 5 is a view in elevation of a detail of construction.

shown the mechanism adapted for operat-v ing upon two traveling webs, upon which printing hasbeen effected by the various cylinders of the press, which cylinders are not shown in the present drawings. It will be understood, however, that a single web or a greater number of webs than shown herein may be operated by the present mechanism.- Feed rolls for the webs are indicated diagrammatically at 5 and 6 and 7 and 8 respectively. Feed roll 7 is positively driven at a given peripheral velocity by gear 10, a gear ll forming a connection between gear 10 and a gear 12 which drives feed roll 5 at a peripheral velocity equal to that at which feed roll 7 is driven. The feed rolls 6 and 8 are rider or idler rolls whichare springpressed into engagement with the positively driven rolls 5 and 7 respectively, and hold thehtraveling webs in close contact therewit Journaled' in an upward extension 9 of the frame work is a cylinder 13 provided with aknife 14 which co-acts with a knife 15 fixed in the frame, said knives co-acting at each rotationof cylinder 13 to sever sheets from the webs which are being delivered by the feed rolls.

16 and 17, respectively, are corrugated.

of cylinder 13 and hold the same in a taut condition during the cutting operation as clearly shown in Fig. 1 of the drawings. When'the knives 14 and 15 have severed the sheets from the webssaid sheets are moved forward from the knives at the speed at which the rolls 16 and 17 are running, thus opening a space between the end of the web and the ends of. the cut sheets. gations of the two rolls sustain such rela- The corrutions to each other that the sheet is not pinched between the rollers, but is merely crimped by the corrugations and carried forward. by friction. The rolls 16 and 17 are highly polished, and, therefore, leave no mark upon the sheet.

Knife cylinder 13 is provided with a gear 22 which is driven by a gear 23, the latter being driven from gear 10 by an intermediate gear 24.. Gear 23 also operates to drive cylinder 16, which in turn drives the cylinder 17, at an equal peripheral velocity.

The cut sheets which, after their delivery fromjcylinders 16 and 17, tend to fall by gravity upon table 2, are engaged and depressed by fingers 25 which are carried upon a shaft 26 journaled in arms 27 extending upwardly from table 2- and bolted thereto. An arm 28 fixed upon shaft 26 extends upwardly therefrom and'is connected with a reciprocatory rod 30, which is suitably guided in a bracket or stop 31 and is similarly guided at its opposite end in a standard 32. A spring 33 coiled about rod 30 is interposed between stop' 31 and a collar 29 fixed a upon rod 30, and this .spring, through rod 30, arm 28 and shaft 26, causes the fingers 25 to move in a downward direction. Rod 30, at its free end, is provided with an antifriction roller 34 which rides upon the periphery of a member 35 fixed upon the shaft of cylinder 13, said member be1ng provided with a sharply cut-away cam portion 37. During the rotation of cylinder 13' this cam portionis engaged by anti-friction roller 34, such engagement allowing spring 33 to depress the fingers 25 as aboveexplained. fIt

will, therefore, be seen that upon each rotation of cylinder 35 the fingers 25. will be vibrated downwardly to depress the cut sheets upon the table 2.

Having thus described the constructionjlof this embodiment of my invention the operation thereof which to a large extent should be obvious is substantiallyas follows. -Upon each rotation of cylinder 13 portions of the webs 4 are projected over knife 15 the ends thereof being received between the cylinders 16 and 17 which operate to hold the webs in taut condition while the knives 14 and 15 are cooperating to sever the sheets. After the knives have severed the sheets said sheets are moved forward from the knives at the speed at which rolls 16 and 17 are running, and open up a space between the end of the web and the end of the sheet which has been out off as above explained. This gives time for the knock-down fingers 25 to depress the sheet upon the table and to return to their raised positions before a second series of sheets has been delivered from the rolls 16 and 17.

It will accordingly be seen that I have provided mechanism well adapted to attain out in an extremely simple yet efiicient manner. Owing to the fact that the feeding of the sheet from the cutting mechanism is accelerated there is no danger of the machine being clogged or rendered inoperative by succeeding sheets being delivered above the knock-down finger before they have assumed their normal positions. The web, moreover, being kept at taut condition during the operation of the knives, the cutting operation is facilitated.

While I have shown my invention as applied -to a press of the above type it will be understood that it may be adapted to other forms of presses or, in fact, to any type of apparatus where it is desired to sever webs into sheets.

As many changes could be made in the L above construction and many apparently widely difierent embodiments of this invention could be made without departing from the sco e thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claims is intended to cover all of the generic and s ecific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
